Abstract
Rheumatoid arthritis (RA) is a chronic multisystemic inflammatory disease with autoimmune features, and of unknown cause, associated with characteristic joint deformities and increased mortality rate. The pathogenesis of this serious disease seems to be multifactorial, where several cytokines, particularly interleukin-1 and tumor necrosis factor-alpha, are strongly involved in the induction and perpetuation of the chronic inflammatory process of the joints in RA and in the systemic manifestations of the disease. Other factors, such as reactive oxygen species and metalloproteinases, may also participate in the destruction of the rheumatoid joint. Current treatments of RA are inadequate in that they only partially control established RA, and despite optimal use of current antirheumatic agents, the outcome of many patients with RA consists of pain, severe functional decline, and premature death. The gloomy recent data regarding the prognosis of RA with the use of the current treatments stress the need for new therapeutic regimens with the ability to effectively control the inflammatory process in the rheumatoid joint and to induce long-term remission or even cure. Controlling the production and the activity of the factors involved in the pathogenesis of the disease represents the major therapeutic goal. Since several factors are involved in the pathogenesis of RA, neutralizing one or some of these factors may be of only limited benefit. In this regard, interleukin-4 may be a very promising agent for an effective treatment of RA, because this cytokine is not limited by its inhibitory effects to a single factor, but rather it inhibits most of the main factors involved in the pathogenesis of the disease. Although recent data strongly support this approach with interleukin-4, controlled long-term clinical trails should be undertaken in order to prove the validity and the effectiveness of this promising approach.
